Stone engraving machine is a processing system which can load NC engraving program and automatically control the movement of engraving machine. It usually consists of engraving program calculation system and NC system.

其工作原理是：计算机通过雕刻软件将需要的雕刻的图形数字化，生成每个步骤的雕刻程序(一般为G代码、HPGL格式文件)，通过USB接口或其他数据传输接口(RS232、RS485等)传输给控制系统，然后控制系统采用特定的算法将输入的路径信息转化为数控信息，控制器把这些信息转化为驱动步进电机或伺服电机的信号(脉冲串)，控制雕刻机X、Y、z三轴的进给.

Its working principle is: the computer digitizes the engraving graphics needed by engraving software, generates the engraving program of each step (generally G code, HPGL format file), and transmits it to the control system through USB interface or other data transmission interfaces (RS232, RS485, etc.), and then the control system uses a specific algorithm to convert the input path information into numerical control information, and the controller converts these information The information is converted into signals (pulse train) to drive stepper motor or servo motor to control the feeding of X, y and Z axes of engraving machine

同时，石材雕刻机的高速旋转主轴带动按加工材质配备的刀具，对固定于机械本体的工件进行铣削，即可雕刻出在计算机上设计的各种平面或立体图形文字，实现雕刻的自动化加工。

At the same time, the high-speed rotating spindle of the stone carving machine drives the cutting tool equipped according to the processing material to mill the workpiece fixed on the machine body, which can carve out various plane or three-dimensional graphics and characters designed on the computer, and realize the automatic processing of carving.

由本系统的设计指标可知，其目标是设计开发一套针对石材雕刻机的控制特点，能满足石材雕刻机控制需求并具有高性价比的普及型中档的嵌入式雕刻机数控系统。因此，本系统需要从速度方面入手，解决好运动的快速性问题，同时兼顾系统的制造成本，使硬件造价控制在预期的范围内。可见，系统的处理速度和成本控制是本系统方案设计应考虑的。

According to the design index of this system, the goal is to design and develop a set of popular and middle-class CNC system for stone carving machine, which can meet the control requirements of stone carving machine and has high cost performance. Therefore, the system needs to start from the speed, focus on solving the problem of fast movement, and take into account the manufacturing cost of the system, so that the hardware cost can be controlled in the expected range. It can be seen that the processing speed and cost control of the system are the key points to be considered in the scheme design of the system.

根据现有数控技术的发展水平，目前提高数控系统处理速度的途径有以下几种：

According to the current development level of CNC technology, there are several ways to improve the processing speed of CNC system

1)PC+高速运动控制卡；
